Technical field
The present invention relates to video transmission equipment, video display apparatus, video display system, video transmission method and computer program.
Background technology
Be expected at and show on the screen that three-dimensional (3D) image and the 3D broadcast service that allows spectators to appreciate three-dimensional video-frequency will be extensively available from now on.In HDMI Ver.1.4, defined the transmission method that is used for the 3D video.Except the frame packaging system, as (being also referred to as Side By Side side by side; SBS or side-by-side system) system etc. also be defined as information (informative) (reference information) system that provides.As the transmission system that is used for 3D rendering, except and heat-extraction system, on also having/(being also referred to as Over-Under, vertical division system, Top/Bottom, Abvoe/Below etc.) system, frame sequential (Frame Sequential down; FSQ) system etc.
The frame packaging system is a system of transmitting left eye video and right eye video in couples.And heat-extraction system is to be the system of transmission of video under right half the state of left half-sum in screen divider.With the situation of the video display apparatus of system compatible side by side under, maybe be from a left side and the right image creation three-dimensional video-frequency of dividing.Yet under the situation of incompatible video display apparatus, left-eye image is presented at the left side of screen respectively, and eye image is presented at the right side of screen.On/following system is the system of transmission of video under second the state of half-sum on screen divider is.Be similar to and heat-extraction system, be/situation of the video display apparatus of following system compatible under, maybe be from the upper and lower image creation three-dimensional video-frequency of dividing.Yet under the situation of incompatible video display apparatus, identical image is shown by vertical symmetry ground.The frame sequential system is a system of sequentially switching and export right eye video flowing and left eye video flowing with the time sharing mode.
When the video of the 3D Video transmission system transmission of passing through the type is for example shared Stereoscopic Video Presentation system (for example the referenced patent document 1 to 3) demonstration through the time of using so-called shutter glasses, possibly cause spectators that video is felt as three-dimensional video-frequency.Frame packaging system and frame sequential system transmissions are used for two video images of left eye and right eye, and therefore they transmit with the transmission rate of the twice of the transmission rate of 2D video transmission under the situation of equal resolution.And heat-extraction system with on/situation of following system under, each vertically or flatly has a half-resolution left eye 3D video and right eye 3D video.Therefore, the 3D video is on the whole with the transmission rate transmission identical with the transmission rate of 2D video.
When the video format of the video of confirming to transmit through HDMI; The video format of 2D video can confirm from following information, like the dot frequency of vision signal, like timing information and the VIC among the AVI InfoFrame (video format identification code, resolution/frame rate information) of Hactive, Hblank, Vblank and Vfreq.Yet; Under the situation of 3D video, except above-mentioned information, also need following information to come the identification video form; As the InfpFrame of information " transmission 3D " that define among the HDMI standard Ver.1.4 (comprise indication transmitting the 3D video information and instruction video the 3D system type (as frame pack, (half the) etc. side by side) information; Details reference HDMI standard Ver.1.4, chapters and sections 8.2.3, appendix H).
When output resolution ratio changed between 2D video and 3D video, if utilize the frame packaging system between 2D video and 3D video, to carry out switching, then video transmission speed also changed.Therefore, with the mode (for example, between 720p and 1080p, switching) that is similar to the resolution changing in the 2D video, when switching, must temporarily stop vision signal output.When HDCP (HDCP system) is used for encrypting and carries out output, when switching, need the HDCP authentication, and blank screen occurs about one to two second.
On the other hand, when utilizing and heat-extraction system is carried out between 2D video and 3D video when switching, if use the big or small and identical frame rate of identical image, then video transmission speed is also identical.Therefore, under the situation of the output that need not stop vision signal, can be only the output of InfoFrame through beginning/stop to transmit 3D information carry out and switch.

Summary of the invention
Technical problem
Yet, under the situation of the amalgam (like television broadcasting) of 3D video and 2D video, can imagine such situation, wherein the 3D video major part and the 2D video that are used for program is used for CM.There is the situation of carrying out the switching between 3D video and the 2D video at short notice; As situation; Wherein carry out and switch, in addition, carry out switching to program major part (3D video/side by side) once more from program major part (3D video/side by side) to CM (2D video).In each case, if blank screen occurs about 1 to 2 second, then exist in problem that can't see the beginning part of video when switching, and this is uncomfortable.Notice that wherein the example via the situation of HDMI output television broadcasting comprises: television broadcasting is through receptions such as STB, HDD registers, and outputs to the situation of HDMI as video; And be recorded in HDD or the dish on TV programme by the situation of playback.

[transmission of 1-6. video data]
[1-6-1. from the 2D video to the switching of video side by side]
At first, with the transfer sequence of describing the video data that when from the 2D video switch to video side by side, video display system, transmits.At first, with describing known video Data Transmission.Fig. 9 is the key diagram that the transfer sequence of the known video data when the switching carried out from the 2D video to video side by side is shown.Fig. 9 passes through to the bottom from the top of figure instruction time." video " instruction video burst; The data sequence of " GCP " indication GCP (general controls grouping); The sequence of " AVI IF " indication AVI (auxiliary video information) InfoFrame, and the data sequence of the InfoFrame of " InfoFrame of transmission 3D information " indication transmission 3D information.
In the prior art, as shown in Figure 9, when the switching carried out from the 2D video to video side by side, after the output of the vision signal that temporarily stops the 2D video, begin the output of the vision signal of video side by side.When allowing HDCP and carrying out transmission, after carrying out the HDCP authentication between source device and the place equipment, carry out change of format.
Shown in Figure 9 with describing from the 2D video to the switching sequence of video side by side.For from the 2D video switch to video side by side, at first, the source device in output video source is provided with AVMUTE in GCP, and sends GCP.Particularly, in the general controls of GCP shown in Figure 10 divided into groups, it was 1 that source device is provided with Set_AVMUTE, and Clear_AVMUTE is set is 0.In the part of " mute (quiet) " indication of the GCP in Fig. 9, this grouping is exported from source device.
Then; The output of the vision signal of 2D video (video) and various types of grouping (GCP and AVIIfoFrame) stops; And at the fixed time section through after, the output of the vision signal of video and various types of grouping side by side (InfoFrame of GCP, AVI InfoFrame and transmission 3D information) begins.Here, if allow HDCP and carry out output, then carry out the HDCP authentication.When accomplishing the HDCP authentication, the AVMUTE among the source device in the output video source cancellation GPC.Particularly, source device is provided with Clear_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Fig. 9, this grouping is exported from source device.
Owing to carry out from the 2D video in this way to the switching of 3D video side by side, therefore stably and safely carry out and switch.Yet when allowing HDCP, blank screen occurs about 2 seconds.Therefore, exist cost for a long time from the 2D video switch to the problem of 3D video side by side.
In order to handle this problem, the present embodiment target is through not stopping vision signal from source device output and do not carry out and carry out under the situation of HDCP authentication from the 2D video to the switching of 3D video side by side, reduces switching time.
Figure 11 is the key diagram that video Data Transmission in the present embodiment is shown when the switching carried out from the 2D video to video side by side.Shown in the sequence of Figure 11, the video Data Transmission target in the present embodiment is through not stopping vision signal from source device output and do not carry out and carry out under the situation of HDCP authentication from the 2D video to the switching of 3D video side by side, reduces switching time.
Figure 12 is from the 2D video to the flow chart of the switching sequence of video side by side in the diagram present embodiment.With use Figure 11 and Figure 12 describe in the present embodiment from the 2D video to the switching sequence of video side by side.
At first, the source device in output video source (video player 100) is provided with AVMUTE in GCP, and sends GCP (step S101) from HDMI hop 111.Particularly, source device (video player 100) is provided with Set_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Clear_AVMUTE is set is 0.In the part that GCP shown in Figure 11 " quiet " indicates, this grouping is exported from source device.
When as stated when step S101 is provided with AVMUTE in GCP, be 3D/ (3D SBS) video (step S102) side by side from the 2D video switch from the video of source device (video player 100) output.Notice that being provided with of AVMUTE can carried out from the 2D video to the identical timing (same number of frames) of switching of video side by side with video among the GCP in step S101.
When as stated at step S102 from the video of source device (video player 100) output from the 2D video switch during for video side by side, source device (video player 100) begins to export the InfoFrame (step S103) of the transmission 3D information of video side by side from HDMI hop 111.The data content of " 3D SBS " among the InfoFrame of transmission 3D information is such content; Wherein " 3D " is made as video format type, and " (half the) side by side " is made as the 3D system type in the data of grouping of shown in Figure 15 " InfoFrame of transmission 3D information ".Showing from the television receiver 300 of the video of video player 100 transmission, be video side by side, the wait (step S104) of insertion predetermined amount of time from the 2D video switch in order to wait for the Video processing pattern.
When waiting for that beginning has been passed through predetermined amount of time, the AVMUTE among the source device in transmission of video source (video player 100) the cancellation GCP, and send GCP (step S105) from HDMI hop 111.Particularly, source device (video player 100) is provided with Clear_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Figure 11, this grouping is exported from source device.
In this way, when from the 2D video switch during for video side by side, control is via the content of HDMI from the grouping of source device (video player 100) output.Therefore, compare, possibly in place equipment (television receiver 300), carry out video switch apace with the situation of carrying out the HDCP authentication.

Figure 14 is from the 2D video to the flow chart of the switching sequence of video side by side in the diagram present embodiment.With use Figure 13 and Figure 14 describe in the present embodiment from the 2D video to the switching sequence of video side by side.
At first, the source device in output video source (video player 100) is provided with AVMUTE in GCP, and sends GCP (step S111) from HDMI hop 111.Particularly, source device (video player 100) is provided with Set_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Clear_AVMUTE is set is 0.In the part that GCP shown in Figure 13 " quiet " indicates, this grouping is exported from source device.
When as stated when step S111 is provided with AVMUTE in GCP, be blank screen (step S112) from the 2D video switch from the video of source device (video player 100) output.Notice that being provided with of AVMUTE can be carried out in the timing (same number of frames) identical with the video switch of video from the 2D video to blank screen among the GCP in step S111, perhaps switch and in GCP, the setting of AVMUTE to carry out before.
When as stated step S112 from the video of source device (video player 100) output when the 2D video switch is blank screen, source device (video player 100) begins to export the InfoFrame (step S113) of the transmission 3D information of video side by side from HDMI hop 111.The data content of " 3D SBS " among the InfoFrame of transmission 3D information is such content; Wherein " 3D " is made as video format type, and " (half the) side by side " is made as the 3D system type in the data of grouping of shown in Figure 15 " InfoFrame of transmission 3D information ".Showing from the television receiver 300 of the video of video player 100 transmission, be video side by side, the wait (step S114) of insertion predetermined amount of time from the 2D video switch in order to wait for the Video processing pattern.
Place equipment (television receiver 300) detects the transmission that begins to transmit the InfoFrame of 3D information through source device, and the interior section of place equipment (television receiver 300) is switched to the pattern (3D display mode) of the pattern of video (pattern side by side) and demonstration 3D video side by side of handling.Particularly, HDMI receiving unit 302 switches to pattern side by side with video processing circuit 314 and figure generative circuit 315, and panel drive circuit 316 is switched to the 3D display mode.In addition, using under the situation of the 3D television receiver (like the television receiver 300 according to present embodiment) of shutter glasses system initiatively, HDMI receiving unit 302 makes glasses drive signal transmitting section 323 begin to control the transmission of the 3D signal of opening and closing of shutter.
If place equipment (television receiver 300) then preferably becomes blank screen (or video of predetermined color/gray scale) with screen display apace being the InfoFrame that receives transmission 3D information side by side during video from the 2D video switch.Usually, after the input of HDMI receiver, video, the television receiver cost is handled video corresponding to the time of some frames, then display video on display floater.Therefore, the data of several frames are retained in the television receiver.Correspondingly; As being right after after the InfoFrame that receives transmission 3D information the result who screen display is become blank screen; If be included in several frame data that are retained in television receiver, possibly avoid the demonstration of damaged image through before and after switching, showing blank screen from the 2D video to the switching of video side by side.
Be used on the display floater 318 of television receiver 300, showing that the example of the method for blank screen comprises: such method; Wherein when HDMI receiving unit 302 detects side by side the InfoFrame of transmission 3D information of (half the); HDMI receiving unit 302 transmission incidents switch to the blank screen data to panel drive circuit so that will arrive the output of display floater 318; And such method, if wherein television receiver 300 uses the LED-backlit systems, then when HDMI receiving unit 302 detected side by side the InfoFrame of transmission 3D information of (half the), its transmission incident was backlight to close to backlight drive circuit 317.
When transponder device (like AV amplifier 200) is inserted between source device (video player 100) and the place equipment (television receiver 300); Transponder device detection resources equipment has begun to transmit the transmission of the InfoFrame of 3D information, and the data of the InfoFrame of the transmission 3D information that receives copy to the register of the inner HDMI hop 206 of transponder device from the register of HDMI receiving unit 203.Then, HDMI hop 206 begins to send the InfoFrame of transmission 3D information.
In some cases, the data replication processes in the transponder device possibly require the time corresponding to a frame or multiframe, and the transmission of the InfoFrame of transmission 3D information maybe be with respect to the video propagation delay.Place equipment receives the HDMI signal that transponder device transmits, and must consider the influence of the delay in the transponder device.If instruction video is the propagation delay of the transmission of the InfoFrame of the transmission 3D information of (half the) side by side with respect to vision signal; Then possibly there is such time period; Although wherein video has switched to side by side (half the), the display mode of television receiver 300 is still indicated the 2D video.Correspondingly, in television receiver 300, be video side by side, the wait of preferably inserting predetermined amount of time from the 2D video switch in order to wait for the Video processing pattern.
When from wait for begin to pass through predetermined amount of time the time, the AVMUTE among the source device in output video source (video player 100) the cancellation GCP, and from HDMI hop 111 transmission GCP (step S115).Particularly, in the general controls of GCP shown in Figure 10 divides into groups, Clear_AVMUTE being set is 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Figure 13, this grouping is exported from source device.
When as stated when step S115 cancels AVMUTE in GCP, switch to video (step S116) side by side from blank screen from the video of source device (video player 100) output.
In this way, when from the 2D video switch during for video side by side, control is via the content of HDMI from the grouping of source device (video player 100) output.Therefore, compare, possibly in place equipment (television receiver 300), carry out video switch apace with the situation of carrying out the HDCP authentication.In addition, through at the 2D video with insert between the video blank screen period side by side, possibly more safely carry out from the 2D video to the video switch of video side by side than sequence shown in Figure 11.
[1-6-2. from video to the switching of 2D video] side by side
Then, with the transfer sequence of describing when the video data that when video switch is the 2D video side by side, video display system, transmits.At first, with describing known video Data Transmission.Figure 16 is the known transfer sequence that illustrates when when video data when video switch is the 2D video side by side.
In the prior art, shown in figure 16, when the switching carried out from video side by side to the 2D video, after the output that temporarily stops the vision signal of video side by side, the output of the vision signal of beginning 2D video.When allowing HDCP and carrying out transmission, after carrying out the HDCP authentication between source device and the place equipment, carry out change of format.
With describe shown in Figure 16 from video side by side to the switching sequence of 2D video.In order to be the 2D video from video switch side by side, at first, the source device in output video source is provided with AVMUTE in GCP.Particularly, in the general controls of GCP shown in Figure 10 divided into groups, it was 1 that source device is provided with Set_AVMUTE, and Clear_AVMUTE is set is 0.In the part of " mute (quiet) " indication of the GCP in Figure 16, this grouping is exported from source device.
Then; The output of the vision signal of video (Video) and various types of grouping side by side (InfoFrame of GCP, AVI IfoFrame and transmission 3D information) stops; And at the fixed time the section through after, the output of the vision signal of 2D video and various types of grouping (GCP and AVI InfoFrame) begins.Here, if allow HDCP and carry out output, then carry out the HDCP authentication.When accomplishing the HDCP authentication, the AVMUTE among the source device in the output video source cancellation GPC.Particularly, source device is provided with Clear_AVMUTE in the general controls of GCP shown in Figure 10 is divided into groups be 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Figure 16, this grouping is exported from source device.
Owing to carry out in this way from video side by side to the switching of 2D video, therefore stably and safely carry out and switch.Yet when allowing HDCP, blank screen occurs about 2 seconds.Therefore, exist cost for a long time from 3D video switch side by side to the problem of 2D video.
In order to handle this problem, the present embodiment target is through not stopping vision signal from source device output and do not carry out and carry out under the situation of HDCP authentication from 3D video side by side to the switching of 2D video, reduces from 3D video side by side to the switching time of 2D video.
Figure 17 is the key diagram that video Data Transmission in the present embodiment is shown when the switching carried out from video side by side to the 2D video.Shown in the sequence of Figure 17, the video Data Transmission target in the present embodiment is through not stopping vision signal from source device output and do not carry out to carry out under the situation of HDCP authentication from video side by side and reduce switching time to the switching of 2D video.
Figure 18 be in the diagram present embodiment from video side by side to the flow chart of the switching sequence of 2D video.With use Figure 17 and Figure 18 describe in the present embodiment from video side by side to the switching sequence of 2D video.
At first, the source device in output video source (video player 100) is provided with AVMUTE in GCP, and sends GCP (step S121) from HDMI hop 111.Particularly, source device (video player 100) is provided with Set_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Clear_AVMUTE is set is 0.In the part that GCP shown in Figure 17 " quiet " indicates, this grouping is exported from source device.
When as stated when step S121 is provided with AVMUTE in GCP, be 2D video (step S122) from the video of source device (video player 100) output from video switch side by side.Then, source device (video player 100) stops to transmit the output (step S123) of the InfoFrame of the 3D information of video side by side.Note, the setting of AVMUTE among the GCP in step S121, can carry out in identical timing (same number of frames) with output at the InfoFrame of the transmission 3D of step S123 information at the video switch of step S122 from video side by side to the 2D video.
When source device (video player 100) stops to transmit the output of the InfoFrame of the 3D information of video side by side; The television receiver 300 that shows the video that transmits from video player 100; In order to wait for that the Video processing pattern is the 2D video from video switch side by side, inserts the wait (step S124) of predetermined amount of time.Can so that the time period that this insertion is waited for be longer than when video from the 2D video switch during for video side by side.Consider place equipment (television receiver 300) detected transmission 3D information InfoFrame output the timeout period that stops and owing to be inserted in the delay that the transponder device (AV amplifier 200) between source device (video player 100) and the place equipment (television receiver 300) causes; If being longer than when video, the time period that makes this insertion wait for during for video side by side, possibly make suitable video be presented on the place equipment (television receiver 300) from the 2D video switch.
When waiting for that beginning has been passed through predetermined amount of time, the AVMUTE among the source device in output video source (video player 100) the cancellation GCP, and send GCP (step S125) from HDMI hop 111.Particularly, source device (video player 100) is provided with Clear_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Figure 17, this grouping is exported from source device.
In this way, when when video switch is the 2D video side by side, control is via the content of HDMI from the grouping of source device (video player 100) output.Therefore, compare, possibly in place equipment (television receiver 300), carry out video switch apace with the situation of carrying out the HDCP authentication.
Yet, if AVMUTE does not work effectively in place equipment (television receiver 300), place equipment (television receiver 300) by error will be side by side Video processing be the 2D video, and exist the video will at least temporarily chaotic possibility that shows.
Suppose this situation; In order to be the 2D video from video switch side by side more safely with video than sequence shown in Figure 17; In the part that AVMUTE has been provided with in GCP; From the vision signal of source device (video player 100) output from video switch side by side is blank screen, and when cancellation AVMUTE in GCP, the vision signal of exporting from source device (video player 100) switches to the 2D video from blank screen.This be because source device (video player 100) have no idea to confirm the response of place equipment (television receiver 300) side from video side by side to the accuracy of the switching timing of 2D video, so the preferred source equipment side is regularly exported blank screen at video switch between video.Through Switch Video and grouping in this way, maybe than sequence shown in Figure 17 more safely carry out video from video side by side to the switching of 2D video.
Figure 19 is the key diagram that another example of video Data Transmission in the present embodiment is shown when the switching carried out from video side by side to the 2D video.Shown in figure 19, another instance object of the video Data Transmission in the present embodiment is through not stopping vision signal from source device output and do not carry out to carry out under the situation of HDCP authentication from video side by side and reduce switching time to the switching of 2D video.In addition, through inserting the blank screen period when video switch is the 2D video side by side at video, can than sequence shown in Figure 17 more safely carry out video from video side by side to the switching of 2D video.
Figure 20 be in the diagram present embodiment from video side by side to the flow chart of the switching sequence of 2D video.With use Figure 19 and Figure 20 describe in the present embodiment from video side by side to the switching sequence of 2D video.
At first, the source device in output video source (video player 100) is provided with AVMUTE in GCP, and sends GCP (step S131) from HDMI hop 111.Particularly, source device (video player 100) is provided with Set_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Clear_AVMUTE is set is 0.In the part that GCP shown in Figure 19 " quiet " indicates, this grouping is exported from source device.
When as stated when step S131 is provided with AVMUTE in GCP, be blank screen (step S132) from the video of source device (video player 100) output from video switch side by side.Notice that being provided with of AVMUTE can carried out to the identical timing of the switching of blank screen (same number of frames) from video side by side with video among the GCP in step S131, perhaps switch and can be in GCP carry out before the setting of AVMUTE.
When as stated step S132 from the video of source device (video player 100) output when video switch is blank screen side by side, source device (video player 100) begins to export and transmits the InfoFrame (step S133) of the 3D information of video side by side.Then, showing from the television receiver 300 of the video of video player 100 transmission, be video side by side, the wait (step S134) of insertion predetermined amount of time from the 2D video switch in order to wait for the Video processing pattern.Can so that the time period that this insertion is waited for be longer than when video from the 2D video switch during for video side by side.
In order to detect the transmission that source device has stopped transmitting the InfoFrame of 3D information, place equipment (television receiver 300) is confirmed the not arrival of grouping of the InfoFrame of transmission 3D information in continuous several frames (for example 10 to 20 frames).When confirming that source device has stopped transmitting the transmission of InfoFrame of 3D information, place equipment (television receiver 300) switches to the pattern (2D tupe) of handling the 2D video and the pattern (2D display mode) of demonstration 2D video with the operator scheme of interior section.Particularly, HDMI receiving unit 302 switches to the 2D tupe with video processing circuit 314 and figure generative circuit 315, and panel drive circuit 316 is switched to the 2D display mode.In addition; Under the situation of the 3D television receiver (like television receiver 300) that uses active shutter glasses system according to present embodiment; HDMI receiving unit 302 for example through stopping to send from glasses drive signal transmitting section 323 the 3D signal of opening and closing of control shutter, makes that initiatively the shutter of shutter glasses 840 is in out state.
If place equipment (television receiver 300) then preferably becomes blank screen with screen display apace at the InfoFrame that when video switch is the 2D video side by side, receives transmission 3D information.Usually, after the input of HDMI receiver, video, the television receiver cost is handled video corresponding to the time of some frames, then display video on display floater.Therefore, the data of several frames are retained in the television receiver.Correspondingly; As being right after after the InfoFrame that receives transmission 3D information the result who screen display is become blank screen; If the switching from video side by side to the 2D video is included in several frame data that are retained in television receiver, possibly avoid the demonstration of damaged image through before and after switching, showing blank screen.
Be similar to above-mentioned from the 2D video to the switching of video side by side; Be used on the display floater 318 of television receiver 300, showing that the example of the method for blank screen comprises: such method; Wherein when HDMI receiving unit 302 detects side by side the InfoFrame of transmission 3D information of (half the); HDMI receiving unit 302 transmission incidents switch to the blank screen data to panel drive circuit so that will arrive the output of display floater 318; And such method, if wherein television receiver 300 uses the LED-backlit systems, then when the HDMI receiving unit detected side by side the InfoFrame of transmission 3D information of (half the), its transmission incident was backlight to close to backlight drive circuit 317.
When transponder device (like AV amplifier 200) is inserted between source device (video player 100) and the place equipment (television receiver 300); For detection resources equipment has stopped transmitting the transmission of the InfoFrame of 3D information, transponder device confirms that the grouping of the InfoFrame of transmission 3D information in continuous several frames does not arrive.After this, transponder device (AV amplifier 200) stops from the grouping of the InfoFrame of HDMID hop 206 output transmission 3D information.The HDMI signal that place equipment (television receiver 300) transmits based on transponder device (AV amplifier 200), the transmission of the InfoFrame of detected transmission 3D information stops.Place equipment (television receiver 300) does not also arrive through the grouping of confirming the InfoFrame of transmission 3D information in continuous several frames, and the transmission of confirming to stop to transmit the InfoFrame of 3D information stops.Correspondingly, transponder device and place equipment both inspections are not sent the InfoFrame of transmission 3D information in continuous several image durations, as a result of, and the double timeout period that needs.For this reason, when transponder device is inserted between source device and the place equipment, have such situation, wherein compare with the switching of vision signal, the definite quilt from video side by side to the switching of 2D video postpones.Correspondingly, consider double time-out time, expectation source device side is provided with the time that video becomes MUTE (blank screen).
When from wait for begin to pass through predetermined amount of time the time, the AVMUTE among the source device in output video source (video player 100) the cancellation GCP, and transmit GCP (step S135) from HDMI hop 111.Particularly, source device (video player 100) is provided with Clear_AVMUTE in the general controls of GCP shown in Figure 10 divides into groups be 1, and Set_AVMUTE is set is 0.In the part of " unmute (not quiet) " indication of the GCP of Figure 19, this grouping is exported from source device.
When as stated when step S135 cancels AVMUTE in GCP, switch to 2D video (step S136) from blank screen from the video of source device (video player 100) output.
In this way, when when video switch is the 2D video side by side, control is via the content of HDMI from the grouping of source device (video player 100) output.Therefore, compare, possibly in place equipment (television receiver 300), carry out video switch apace with the situation of carrying out the HDCP authentication.In addition, through inserting between video and the 2D video blank screen period side by side, possibly more safely carry out from video side by side to the video switch of 2D video than sequence shown in Figure 17.
With describing when another transfer sequence when video switch is to the 2D video side by side.Figure 21 is the key diagram that another example of video Data Transmission in the present embodiment is shown when the switching carried out from video side by side to the 2D video.Shown in figure 21, another instance object of the video Data Transmission in the present embodiment is through not stopping vision signal from source device output and do not carry out to carry out under the situation of HDCP authentication from video side by side and reduce switching time to the switching of 2D video.In addition,, be similar to sequence shown in Figure 19 through inserting the blank screen period when video switch is the 2D video side by side at video, can than sequence shown in Figure 17 more safely carry out video from video side by side to the switching of 2D video.
Being different from sequence shown in Figure 19, in sequence shown in Figure 21, is being the timing of 2D video from video switch side by side, and the value of the InfoFrame of transmission 3D information is from becoming 2D side by side, and this InfoFrame is transferred to place equipment from source device.When exporting side by side video, in the data of the grouping of " InfoFrame of transmission 3D information " shown in Figure 15, " 3D " is made as video format type, and " (half the) side by side " is made as the 3D system type.On the other hand, when output 2D video, " No Information (2D) " is made as video format type, and 0 be made as the 3D system type value (because the video of transmission is not 3D, so corresponding field is made as reservation).In addition, verification and data (it is corresponding to " CheckSum " shown in Figure 15) also appear in the grouping of the InfoFrame that transmits 3D information.
Correspondingly, the change of the InfoFrame of transmission 3D information can be checked through confirming verification and data.When the InfoFrame of transmission 3D information changed, the HDMI receiving unit 203 and 302 of place equipment (television receiver 300) and transponder device (AV amplifier 200) can detect the change of the InfoFrame of transmission 3D information respectively immediately.This is because timeout treatment becomes necessary, as under the situation of the transmission that stops to divide into groups, shown in Figure 19 and 20.
Therefore; In sequence shown in Figure 21; Compare with sequence shown in Figure 19, place equipment (television receiver 300) and transponder device (AV amplifier 200) can be exactly and at short notice (for about 0 to 1 frame of each equipment) detect from video side by side to the video switch of 2D video.As a result, although when in source device (video player 100) when video switch is the 2D video side by side, before and after switching, provide quiet, compare with sequence shown in Figure 19, possibly reduce this quiet time.In addition, reduced the time period that place equipment (television receiver 300) and transponder device (AV amplifier 200) detect video switch.Therefore, the situation that possibly after the quiet period finishes, avoid damaged image to show fully increases.
Notice that the InfoFrame of transmission 3D information is the grouping that need in the 2D video section, not send basically.Therefore, from video when video switch is the 2D video side by side through behind the predetermined amount of time, source device can stop to transmit the transmission of the InfoFrame of 3D information.In addition; When the transmission that detects the InfoFrame of indication 3D/ transmission 3D information side by side when transponder device has stopped; Shown in the sequence among Figure 17 and Figure 19; Substitute transmission output, that transmit the InfoFrame of 3D information that stops as from transponder device; If the output instruction video is the 2D InfoFrame of information " transmission 3D ", in the sequence shown in figure 21, if be that the front and back of the transmission of 2D " InfoFrame of transmission 3D information " are provided with the AVMUTE period perhaps at the beginning instruction video; And the video of output becomes blank screen (image of the monochrome on the perhaps whole screen, be implemented as 2D or can watch side by side and do not have an image of uncomfortable feeling no matter show), also possibly reduce up to the place Equipment Inspection to from video side by side to the time of delay of the switching of 2D video.
2. conclusion
As stated,,, do not carry out the HDCP authentication, and before and after switching, stop the output of video or show the video of blank screen (or predetermined color/gray scale) when when the 2D video switch is the 3D video or when the 3D video switch is the 2D video according to embodiments of the invention.Therefore, possibly reduce the time of switching requirement.In place equipment (television receiver 300), possibly avoid as will be side by side Video processing be the 2D video or the 2D Video processing shown damaged image for the result of video side by side on screen.
When the 3D video switch is the 2D video; Substitute the InfoFrame that stops to send transmission 3D information from source device (video player 100); Through the content of change from the grouping of the InfoFrame of the transmission 3D information of source device transmission; The quiet period of video switch front and back maybe be reduced, and therefore the time of video switch requirement maybe be further reduced.
Notice that above-mentioned a series of processing can be carried out by hardware perhaps can be by software executing.When by software executing, stored program storage medium for example can be incorporated in each of video player 100, AV amplifier 200 and television receiver 300.Then, such program can or incorporate that other control appliances in each of video player 100, AV amplifier 200 and television receiver 300 are read and order is carried out by CPU (CPU), DSP (digital signal processor) into.
In addition, in the foregoing description, the source device of having described output video is a video player.Yet, the invention is not restricted to this example.For example, source device can be the game machine of fixing, STB, personal computer or other messaging devices that receives broadcast wave, and perhaps it can be the HDMI output in the transponder device.In other words, any equipment can be used as source device, and the present invention can be applied to it, if it can transmitting video data to other equipment.
The preferred embodiments of the present invention have been described with reference to the drawings above, certainly, have the invention is not restricted to above-mentioned example.Those skilled in the art can find various the substituting and modification in the claim scope, and should be understood that they will occur in technical scope of the present invention naturally.
